Parameters to be measured at each station include:
Instrument-based CTD (yields temperature, salinity, depth), pH, chlorophyll, dissolved oxygen, and turbidity) – [NOAA and others] Light spectra over the whole water column - hyperspectral -[NASA]
Water sample (bottle or pumped) -based Nutrients [UMD] Primary Production, Respiration [UMD] Phytoplankton (algal) pigments, dissolved organic, carbon, particulate organic carbon [UMD, NASA] Phytoplankton DNA, phytoplankton size spectra [UMD] Source tracking with fluorescence indicators and stable isotopes. Bacteria samples [UMD]
Net tow-based Plankton collection with nets [UMD – HPL]

Summary
• Set timing for response operations to meet several disciplines – we may have been too early for biogeochemical signal from Irene
• More data from BC cruise Aug 31 coming
• Total Suspended Matter algorithm proved useful; now daily from NOAA; in situ sampling providing extremes for satellite product testing
• Profiles Sep 13, Sep 20 exhibit subsurface clarity and then settling of sediment plume just south of Bay Bridge
• Recommend full science team participation in Fall workshop – NASA team, Ondrusek et al.
• Recommend data manager activity to assemble special event dataset, compile literature
